Summer is in full swing, and many are enjoying the sunshine and warmer weather, but it’s also a busy season for Illinois’ electric cooperatives.
Irrigation, construction and improvement projects are underway, annual meetings are taking place, and homes and businesses are using more electricity to keep cool.
It takes a lot of electricity to meet all this demand, and electric utilities must ensure there is power available around the clock. So, have you ever wondered how your electric co-op forecasts electricity on the grid?
Electric load forecasting is an important activity that many co-ops perform every day. When you hear things like “peak demand” or “prices are spiking,” it can sound complex and daunting. At the center of these challenges is forecasting.
Electric co-ops use a variety of analytics to predict factors like weather, sunshine, wind, cloud coverage, rain, power generation and even the future use of electricity, including how much and when it will be used.
All of this information helps co-ops plan and prepare for the next day, week or month to ensure the grid runs smoothly, so we can all enjoy the summer with our family and friends. This practice is called “load forecasting.”
With the changing electric grid — from more renewable energy sources showing up on the system to growing communities that need more electricity — load forecasting is crucial for managing its health.
Accurate forecasting is essential for grid operators to allocate power generation effectively. Proper forecasting aids in scheduling power plants and managing fuel supplies. This leads to reduced operational costs and minimized waste in electricity production, transmission and distribution.
Maintaining stability is a primary concern for electric co-ops, because the grid must constantly balance electricity supply with demand. Load forecasting enables co-ops to anticipate electric peaks and supply disturbances, and helps prevent the grid from failing, which can lead to blackouts.
The integration of renewable energy sources like wind and solar adds complexity to load forecasting. Accurate forecasts help optimize the use of variable renewable energy. Combining load forecasts with renewable generation forecasts helps optimize the grid with tremendous economic benefits.
Short-term forecasts (daily or weekly) give grid operators the necessary data to make informed decisions on what type of power generation to schedule and what electric market purchases or sales need to be made, and to mitigate risks of supply shortages or surpluses so that you can get the most affordable electricity to your home or business.
Additionally, load forecasting informs future planning for infrastructure development, grid expansion, upgrades and interconnections. With the growing demand for electricity, ensuring the grid can handle future increased use is essential and helps maintain reliability over time.
Forecasting electricity demand allows for adaptability to changing power generation sources and demand patterns. It’s an important piece of the puzzle for maintaining a reliable, efficient and cost-effective grid.
